What is my favorite invention?

We knew there had been many inventions at the last century, for example,electric light bulb, telephone, phonograph, mimeograph machine, automobile,airplane, atomic weapon, computer and so on. What is my favorite invention?

Personally, my favorite invention should be computer. In the old days, manyscientists took much time to calculate and deal with research data, so theeffective time in doing research was relatively shortened. For millions of timesof calculating per second by computer, the researchers may have enough time tostudy more important issues. The processing of experiment results became verysimple and easy. Aren’t those all evidences that the computer is one of thegreatest inventions in the last century, are those?
